Capacity Testing and 20 HR Rating
I'm thinking about doing a capacity test on my four GC2's. They have a 20hr rating of 215Ah. One thing I'm curious about is how the 20hr rating would have been determined. Being 6v, would they h...

I should provide an example to illustrate a text book look at kWh evaluation.
A particular battery is charged from 50% SOC to 100% SOC using a hydrometer to establish status.
.424 kWh is delivered
A 2nd like-battery is tested and reveals
.484 kWh is needed
Obviously the CEF is different. By comparitive means real-time can enter the picture. By simple ddeduction several scenarios emerge as possible plausible explanations. Differential energy transaction values can reveal problems that no ampere hour meter on earth can interpret. ENERGY needed to recover a battery not mere ampere hours is key. Charging a battery entails a ascending voltage value. An amp hour meter is blind to this and blind on voltage degradation during discharge. If you wish to know energy relationships use kWh.
Landyacht would flip had he realized energy differential comparison in his "Screwy 31".
